Changeset 32374 for trunk/PS-IPP-Config

Message:

Added method redirect_to_logfile to PS::IPP::Config class. This checks for an existing log file.
If found renames it by appending a date string, then redirects STDOUT and STDERR to the new log file.
The name of the renamed file is included in the log.
In chip_imfile.pl use the new function and stop passing the -log parameter to ppImage. This should
lead to a consistent log output.
